I have bad posture when I am sitting. When I am standing, I can keep my back straight rather easily. My upper back slumps forward when I am sitting. I do have upper back problems, perhaps related to a life of bad posture.
My eyes are very nearsighted and I wear glasses and contacts. I feel crippled without my seeing devices, like poor Piggy on that dreadful island.
And there’s no way I would use a pocket protector! I can barely stand having anything in my pockets.
As for body language, I have been told that I present “weird,” inappropriate, or insecure body language.
